The aged Karloff stars as a disgraced hypnotist, eager to try out his new thought transferal device at the urge of his domineering wife (Lacey). Finding an ideal subject in a jaded youth (Ogilvy), the couple discover they can vicariously experience his every sensation while controlling his actions. Karloff wishes his invention to be used for the crippled and elderly to take a virtual vacation, while his wife revels in the thrill of committing various crimes through the young man. Her wishes increase from theft to murder. After she has successfully shattered Ogilvy's life and relationships, it boils down to a battle of wits between the two for control of the young man's psyche. It plays like an episode of the original Outer Limits series, with the couple's venture into realms man was not meant to explore, and tragic denouement although there is no Control Voice to lull us back to normality or offer a moral here.
Michael Reeves made one other film, the stunning Witchfinder General before taking his own life at the age of twenty-five. Who knows what the film's enfant terrible director might have accomplished had he lived? From subtle tricks of lighting, and the use of a story that fits the budget, to imaginative shots and an emphasis on action, it contains all the elements today's independent filmmakers should take note of. It is worth noting Ogilvy would later take on the role of mad scientist involved in mind control techniques in Fugitive Mind.
While dated in many aspects, it's a shame this film is all but forgotten, and unavailable commercially.
